Choose two
  • A It uses Telnet to report system issues.
  • B The administrator can make configuration updates from the CLI.
  • C It uses northbound and southbound APIs to communicate between architectural layers.
  • D It decentralizes the control plane, which allows each device to make its own forwarding decisions.
  • E It moves the control plane to a central point.
Explanation

A controller-based network centralizes the control plane in a controller rather than leaving control logic distributed on each individual device. It also relies on northbound APIs to communicate with applications and orchestration layers, and southbound APIs to communicate with the underlying network devices and infrastructure.
